Rated breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, 50 Hz — enough for most commercial and light-industrial panelboards where the prospective fault current stays under that threshold. The DC rating is 60 V, which covers control-circuit rails and battery-backed supplies. Combined tunnel terminals top and bottom accept Cu conductors; tighten to 3.5 Nm per the terminal torque spec.
Vibration resistance tested to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 s).
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, 50 Hz. The DC rating is 60 V.
The breaker is halogen-free and silicon-free, rated for pollution degree 3 and overvoltage category III. It is designed for mechanical engineering/industry environments and is suitable for EMC environment B.
